hello everyone, I am 17 this year. I have noticed that my penis is shorter than guys my age. About only 1 inch when unerected and 2-3 inches when erected. I am pretty embarrassed to consult my general practitioner about this problem. And at night when I am about to sleep, My foreskin and testicular balls will become very itchy till I have to scratch it to relieve the itchiness or I can't sleep at all at night.
